Embodiment Construction
[0052] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific examples. It should be noted that this example is only used to illustrate the present invention and is not intended to limit the scope of the present invention, and modifications to various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the appended claims of the present application.
[0053] Such as figure 1 As shown, in view of the problem that the prediction accuracy of photovoltaic output power affects the safe scheduling and stable operation of the system, the present invention proposes a short-term photovoltaic power prediction method based on EEMD and combined kernel RVM. First, according to the weather conditions, the photovoltaic power data are divided into four types: sunny day, cloudy day, rainy day and cloudy day, and modeled separately to ensure the consisten...
